Hello, I’m need some advice on how a contactor is wired please and where the neutral go. I’m told it is connected to eco 7 and controls 3 heaters in a domestic flat. It stopped working after an electrician did something on a different circuit in the consumer unit.
The contactor is an Eaton...
I think I should look again for the loose connection on the CPC, I’m pretty sure the cable is 2.5-1.5.
does the result have to be within 1.67 or is it allowed to be slightly over? I was told 1.67 is what we would expect to see so when would you start to look into it?

if the radial off the ring via the spur is higher than 1.08 but less than the allowed value after a 13amp fuse, which value would you write on the test form?
Thanks

Hello,
How would you go about testing outside lights on an EICR if they are supplied off an outside socket?
The sockets are supplied off the downstairs ring main, inside there is a 13amp switched fuse spur, then a double pole isolator running outside to 3 x double outdoor sockets all run in...
